How do I handle an UnresolvedImport Eclipse (Python)

Question

When I write import MySQLdb in Eclipse using the PyDev plugin, I get an unresolved import. However, the program runs without error. I can add an annotation to get

Answer 1

I once had a similar problem on Windows (never encountered this on Linux though) and I discovered that I had to include the .egg directory of my library to my PYTHONPATH.

For example my PYTHONPATH (Pydev/Interpreter - Python/Libraries) included:

C:\Python26\Lib\site-packages

and I had to add:

C:\Python26\Lib\site-packages\jinja2-2.2.1-py2.6.egg

to use jinja.

Answer 2

Fixed this by doing two things:

1) Added MySQLdb egg to the PYTHONPATH under Window->Preferences->Preferences->PyDev->Python Interpreter.

C:\Python26\Lib\site-packages\MySQL_python-1.2.3c1-py2.6-win32.egg

2) Close and re-open the .py file that had the red x.

Answer 3

import MySQLdb

If this code show error like this:

Unresolved import: MySQLdb

you should add D:\Python27\Lib\site-packages\MySQLdb to your sys.path.

D:\Python27\Lib\site-packages\MySQLdb is this location where you install MySQLdb in your computer disk. After this step, the error will disappear.

Answer 4

I had a similar issue and the following is what I did to solve my issue. I have a Windows 8 Machine, Python 2.7 installed and running my stuff through eclipse.

Some Background:

When I did an easy install it tries to install MySQL-python 1.2.5 which failed with an error: Unable to find vcvarsall.bat. I did an easy_install of pip and tried the pip install which also failed with a similar error. They both reference vcvarsall.bat which is something to do with visual studio, since I don't have visual studio on my machine, it left me looking for a different solution, which I share below.

The Solution:

1. Reinstall python 2.7.8 from 2.7.8 from https://www.python.org/download this will add any missing registry settings, which is required by the next install.
2. Install 1.2.4 from http://pypi.python.org/pypi/MySQL-python/1.2.4

After I did both of those installs, I reopened eclipse and got a prompt to update the paths of eclipse which I accepted, after that I was able to query my MySQL db.

Answer 5

This surely works I just tried it with Pmw package. Unzip package in site-packages. Then remove python interpreter from eclipse and then add it again. Your import errors shall go away. also you may want add module to forced builtins. See How do I fix PyDev "Undefined variable from import" errors? and http://pydev.org/manual_101_interpreter.html

Answer 6

Adding the egg works, but the error remains. The solution for that error can be found by adding

#@UnresolvedImport

To the import statement, as in:

import web #@UnresolvedImport
